Embodiment Construction

[0023] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0024] figure 1 It is a perspective view which shows the rubber crawler 1 of this embodiment. like figure 1 As shown, the rubber crawler 1 of this embodiment includes a crawler main body 2 formed of rubber in an endless belt shape, a plurality of mandrels 3 embedded in the crawler main body 2 , and a tensile member 4 embedded in the crawler main body 2 .

[0025] In this specification, the track circumferential direction is the rotation direction of the rubber track 1, which is equivalent to figure 1 The reference sign a indicates the direction. In addition, the track width direction is the axial direction of the driving wheel, floating wheel and roller when the rubber track 1 is installed on the vehicle, which is equivalent to figure 1 The direction indicated by the reference sign b. In addition, the track thickness direction is a direction perpendicular to the track ci...

Abstract

The rubber crawler track provided by the invention can improve the operability of assembling the mandrel bar and the tensile body for suppressing the deformation of the lugs. A rubber crawler (1) includes: a crawler main body (2) formed in an endless belt shape from rubber, a plurality of mandrels (3) embedded in the crawler main body (2), and Extended tensile body (4). A plurality of lugs (5) protruding toward the outer peripheral side (co) of the crawler belt are formed on the outer peripheral surface (2a) of the crawler main body (2). Each mandrel (3) is integrally provided with: a first wing portion (3a), which extends along the track width direction (b) and is embedded in the lug (4); a second wing portion (3b), which is larger than the first wing portion. The portion (3a) extends along the track width direction (b) near the track inner peripheral side (ci) with a gap (3e). The outer side of the gap (3e) in the track width direction (b) is open, and the tensile body (4) is arranged in the gap (3e).

Description

technical field [0001] The invention relates to a rubber crawler reinforced by a mandrel and a tensile body. Background technique [0002] Conventionally, a rubber crawler is known that includes a crawler main body formed of rubber in an endless belt shape, a plurality of mandrels embedded in the crawler main body, and a tensile body embedded in the crawler main body. In order to transmit driving force and traction force during running, a plurality of lugs protruding toward the outer peripheral side of the crawler belt are formed on the crawler belt main body. [0003] The crawler main body is reinforced by tension using the wings of the mandrel extending in the crawler width direction and the tensile body extending in the crawler circumferential direction, thereby maintaining its shape while running. On the other hand, the lugs located closer to the outer peripheral side of the crawler belt than the tensile member may be deformed largely due to ground contact during runnin...
